I don't get it. You haven't used map in void context. Also, I'm not convinced that you haven't purposefully written your code inefficiently just to prove that map is useful. Why do you have the intermediate grep when an if in the for loop would do just fine? Sure, copying lists around is *fairly* cheap, but we come to my original point: Did you actually take a step back before designing your code, to ensure that it works best? Or did you just string map and grep together until it worked the way you wanted it to?
